What's a good source for used 129 SL parts?
 

Looking for a good source of used 129 SL parts. I have a 91 and would like to buy body parts to update it.

E-bay
 

There are always tons of w-129 parts on E-Bay.

Try www.car-part.com

I've had good luck with the yards that post on this site. Just fill in the car type, and it will tell you where the parts are. They list them by price.
Don't bother sending an email to these yards; my experience is that they won't answer. Call them on the phone. I've found prices are negotiable.
